Further, further, box body has USB interface side and is set with boot seal, has the inserted into gap inserted for USB device outside boot seal.
Further, the flexible restoring organ of dust-proof partition board is spring, and dust-proof partition board upper end and anti-dust seat roof have the detent stretched into for spring respectively, and both ends of the spring supports location with the detent of dust-proof partition board upper end and anti-dust seat roof respectively.
Further, box body comprises upper cover and lower cover, and upper cover has barb, under cover and be provided with the groove corresponding with described barb, upper cover and lower cover are fastened by barb and groove.
Further, anti-dust seat is fixedly connected with by bolt is removable with currency counting and detecting machine backboard.
Further, cartridge upper surface has grafting bearing mark.
Further, the sidewall that box body has Pin contact extends at least one locating button pin, anti-dust seat has the cavity stretched into for box body locating button, and box body locating button pin has the hemisphere locating convex block arranged down, has the hemisphere location dimples be directed upwardly in anti-dust seat cavity.
The beneficial effects of the utility model are: by arranging interface switching device, when Single Chip Microcomputer (SCM) program needs upgrading, as long as pull up the connector of display unit, plug of the present utility model is inserted on the pin type interface of currency counting and detecting machine, in connection, data communication line is connected with computer, and just can write in single-chip microcomputer by needing the computer program of upgrading, its structure is simple, conversion is convenient, very practical on currency counting and detecting machine; The two ends of interface switching device all arrange dust guard, and prevent piling up dust and cause loose contact and effectively prevent interface from colliding causing distortion, syndeton is stablized, currency counting and detecting machine complete machine long service life.
